Development of marine probiotics: prospects and approach.

The term probiotics stands for bacterial strain acting for the upliftment of beneficial gut microflora as well as restricting the growth of decay or disease causing bacteria and other agents. They protect us from disease causing microorganisms and are vital for the digestion of nutrients and food. Researchers are now trying to explore the possibilities of therapeutic applications of probiotics in inflammatory bowel disease, treating diarrhea, eczema prevention in children, and reducing bladder cancer recurrence and urinary tract infections. The best known probiotic strains are Bifidobacteria, Lactobacilli, and Streptococcus thermophilus and can be found in food products such as yoghurts, fermented and unfermented milk, miso, tempeh, and some juices and soy beverages. Thus, as a substitute to the use of antibiotics, the dietary supplementation with probiotic bacteria is being widely employed in the aquaculture industry. This chapter is an attempt to shift the paradigm of research in probiotic area to the marine environment and to find ways of expanding the research in marine probiotics development.
